ID the type of Losmandy Motor you have by it's Fins.


This is what the current version of the High Torque motor looks like.
This motor is reported to have higher torque than any previous motor.
The part number is SVM-HT and can be ordered from here Current price is $220.00USA.
This motor is 2.810" (71.37mm) long with a shaft diameter of 0.1250" (3.18MM). Also notice that this motor is larger in diameter that the Maxon motor was. That is the reason that the fins only come down about 50% of the motor (5 fins total). The mounting disk on all three motors are designed to fit the Gemini Servo Gearbox. These motors do not include the Gemini Servo Gearbox, so if you need that it must be ordered separately. See image here. Also make sure you ask for the mounting screws, as the ones for previous motors will not work in this motor, they are too long.  Also the screw length to mount them is 15mm of thread.  The 15 mm length does not include the head size.

Be advised that Scott Losmandy has the cases for all the motors he uses made custom so that the motor and encoder will fit the way it is suppose to.  The motors inside these cases are purchased and placed into these custom cases The motor themselves are from an undisclosed manufacture .  The only place to get the motors with the mounting bracket manufactured into the case and the Encoder mounted on the end is from Losmandy.com

Mr. Rainer Ehlert published a PDF on the Gemini_Users group on repairing the encoders of the Standard motor.  He has given me permission to host it here. Thanks Rainer for all the help you have provide in the past.
